<p>
    此工具向导中的步骤与相应任务中的那些步骤相匹配。Rational XDE (TM) 联机帮助中主题的链接标有<img height="16" alt="帮助手册图标" src="./../../../core.base_rup/resources/helpbook.gif"     width="16" />。
</p>
<p>
    此工具向导假设已根据 <a class="elementLinkWithUserText" href="./../../../core.base_rup/guidances/whitepapers/model_structure_guidelines_for_rational_xde_developer_6D2FD64A.html" guid="2.67081400527339E-306">XDE 模型构造指南</a>创建了用例模型。
</p>
<p>
    在本工具向导中执行以下步骤：

<p>
    找到参与者以后，请记录您的结果，如下：
</p>
<ol>
    <li>
        打开“用例模型”。
    </li>
    <li>
        浏览到将包含参与者的包。请参阅 <a class="elementLinkWithUserText" href="./../../../core.base_rup/guidances/whitepapers/model_structure_guidelines_for_rational_xde_developer_6D2FD64A.html" guid="2.67081400527339E-306">Rational XDE 模型构造指南</a>。
    </li>
    <li>
        创建一个图来包含参与者，为图的类型选择用例图。参考：<img alt="帮助手册图标" src="./../../../core.base_rup/resources/helpbook.gif" /> <i>Adding Diagrams</i>。 
        <!--//ReferenceHelpTopic(topicTitle,"rs","rs_t_add_dgm"); -->
    </li>
    <li>
        将参与者添加到图中。请参阅 <img alt="帮助手册图标" src="./../../../core.base_rup/resources/helpbook.gif" /> <i>Adding Shapes to Diagrams</i> 
        <!--Removed javascript  ReferenceHelpTopic(topicTitle,"rs","rs_t_add_shp_dgm"); -->。
    </li>
    <li>
        以简短描述对每个参与者作注释。请参阅 <img alt="帮助手册图标" src="./../../../core.base_rup/resources/helpbook.gif" /> <i>Documenting Model Elements</i> 
        <!--Removed javascript     ReferenceHelpTopic(topicTitle,"rs","rs_t_doc_model_elem"); -->.
    </li>
</ol>

    </li>
    <li>
        提供事件的简短描述和概要流程。这可以在模型元素上进行初始注释。 （请参阅<img alt="帮助手册图标" src="./../../../core.base_rup/resources/helpbook.gif" /><i>记录模型元素</i> 
        <!--ReferenceHelpTopic(topicTitle,"rs","rs_t_doc_model_elem"); -->。）也可以使用 RUP 为<a class="elementLinkWithUserText" href="./../../../core.base_rup/workproducts/rup_usecase_A5D30E62.html" guid="{B1526BC5-E346-42CB-A08A-3C0D7F382407}">工作产品：用例</a>提供的模板并将其附加到模型中的用例上。请参阅 <img alt="帮助手册图标"         src="./../../../core.base_rup/resources/helpbook.gif" /><i>Linking External Files to Model Elements</i>

<h3>
    <a id="Describe how Actors and Use Cases Interact" name="Describe how Actors and Use Cases Interact">描述参与者与用例的交互方式</a>
</h3>
<p>
    按照下列这些步骤，描述参与者和用例之间的交互：
</p>
<ol>
    <li>
        将先前创建的参与者添加到包含用例的用例图中。请参阅 <img alt="帮助手册图标" src="./../../../core.base_rup/resources/helpbook.gif" /><i>Adding Shapes to Diagrams</i> 
        <!--Removed javascript          //ReferenceHelpTopic(topicTitle,"rs","rs_t_add_shp_dgm"); -->。
    </li>
    <li>
        添加参与者和用例之间的通信关联。（请参阅 <img alt="帮助手册图标" src="./../../../core.base_rup/resources/helpbook.gif" /><i>Adding Association Relationships</i>
        <!--Removed javascript          //ReferenceHelpTopic(topicTitle,"rs","rs_t_add_assoc_rels"); -->。）如果关联仅在一个方向可导航，请选择有方向的关联，首先单击使用者形状，然后单击提供端形状。
    </li>
    <li>
        （可选）描述关联。请参阅 <img alt="帮助手册图标" src="./../../../core.base_rup/resources/helpbook.gif" /> <i>Documenting Model Elements</i> 
        <!--Removed javascript          //ReferenceHelpTopic(topicTitle,"rs","rs_t_doc_model_elem"); -->.
    </li>
    <li>
        （可选）添加角色的多重性。请参阅 <img alt="帮助手册图标" src="./../../../core.base_rup/resources/helpbook.gif" /><i>Specifying Multiplicity in Association
        Ends</i> <!--//ReferenceHelpTopic(topicTitle,"rs","rs_t_spec_multip_assoc"); -->。
    </li>
</ol>
